Introduction

When it comes to choosing a microcontroller for your embedded system project, there are many factors to consider. Two popular options from STMicroelectronics are the STM32H723 and STM32H743. Both of these microcontrollers belong to the STM32H7 series and offer a wide range of features and capabilities. In this article, we will compare the attributes of the STM32H723 and STM32H743 to help you make an informed decision for your project.

Performance

One of the key differences between the STM32H723 and STM32H743 is their performance. The STM32H723 is based on the Arm Cortex-M7 core running at up to 550 MHz, while the STM32H743 is based on the Arm Cortex-M7 core running at up to 480 MHz. This means that the STM32H723 offers slightly higher performance compared to the STM32H743. If your project requires high computational power, the STM32H723 may be the better choice.

Memory

Another important factor to consider when choosing a microcontroller is the amount of memory it offers. The STM32H723 and STM32H743 both come with a range of memory options, including Flash memory, SRAM, and external memory interfaces. The STM32H723 typically offers more memory options compared to the STM32H743, making it suitable for applications that require a large amount of memory for data storage and processing.

Connectivity

Connectivity is a crucial aspect of any embedded system, and both the STM32H723 and STM32H743 offer a variety of connectivity options. These microcontrollers come with multiple communication interfaces, including UART, SPI, I2C, USB, Ethernet, and CAN. The STM32H743, however, offers more connectivity options compared to the STM32H723, making it suitable for applications that require a high level of connectivity with external devices.

Security

Security is becoming increasingly important in embedded systems, especially in applications that handle sensitive data. Both the STM32H723 and STM32H743 come with a range of security features, including hardware cryptographic accelerators, secure boot, and secure firmware update mechanisms. However, the STM32H743 offers more advanced security features compared to the STM32H723, making it a better choice for applications that require a high level of security.

Power Consumption

Power consumption is a critical consideration in battery-powered embedded systems. The STM32H723 and STM32H743 both offer low-power modes to help reduce power consumption when the microcontroller is not in use. However, the STM32H723 typically consumes less power compared to the STM32H743, making it a better choice for applications that require low power consumption.

Development Tools

When it comes to developing software for microcontrollers, having access to a comprehensive set of development tools is essential. Both the STM32H723 and STM32H743 are supported by STMicroelectronics' STM32Cube development ecosystem, which includes a range of software tools, middleware, and libraries to help streamline the development process. Whether you choose the STM32H723 or STM32H743, you can benefit from a rich set of development tools to help you bring your project to life.

Conclusion

In conclusion, the STM32H723 and STM32H743 are both powerful microcontrollers with a wide range of features and capabilities. The STM32H723 offers higher performance and lower power consumption, making it suitable for applications that require high computational power and low power consumption. On the other hand, the STM32H743 offers more memory and connectivity options, as well as advanced security features, making it a better choice for applications that require a high level of memory, connectivity, and security. Ultimately, the choice between the STM32H723 and STM32H743 will depend on the specific requirements of your project.
